Explanation:
Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification segment below, the definition of the query has been mentioned.
Explanation:
This shows that perhaps the distinctions between individuals living in a culture or geographical region are often based on ethnicity and ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair texture, individual capacity for heat resistance, and food taste. Throughout certain races or ethnic groups, these similar traits bring them together. The young government corresponding to a certain race is often asked to follow the custom adopted by those belonging to a certain particular demographic. It is assumed that persons belonging to that same race follow these rituals mostly to solve difficulties they have experienced personally due to errors perpetrated by certain ancestors.Beta receptors:
O are cholinergic.
O bind acetylcholine.
O bind norepinephrine.
O bind the toxin muscarine.
Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 1st, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 1st. On February 1st, two residents developed TB. On April 1st, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.
What was the prevalence of TB in the screened community on January 1st?
Answer: 5%
Explanation:
The Prevalence rate is the term used to describe the percentage of a population that have contacted the disease being tested for. It is usually done over a certain period or a certain time.
The prevalence of TB in the screened community on January 1st therefore is;
= Number of infected/ No. of Tested residents
= 10/200
= 5%

Each strand of a DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A segment of a DNA strand is shown.
3’ GATCGATC 5’
Which complementary DNA strand pairs correctly with the strand above?
A. 5’ CTAGCTAG 3’
B. 5’ GATCGATC 3’
C. 5’ CUAGCUAG 3’
D. 5’ CATCGATC 3’
Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.
What is complementary base pairing in DNA molecule?Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.
This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.
Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.
For instance, a complementary DNA strand will have the nucleotide sequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.
Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

Why do some dominant traits have two different types of alleles?
Answer:
you inherit 2 alleles for each genes. one comes from your biological mom and the other comes from you biological father. if the alleles are identical like when both your parents have brown eyes and that it will cause you to have brown eye color. some alleles are dominant while the rest are recessive. the dominant trait is more stronger than recessive trait. It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth. Additionally, one allele may be dominant for one trait but not others.

B. create better looking rice
c.grow rice under drought conditions
D.create rice that contains more nutrients
Answer:
Golden rice is a genetically modified, biofortified crop. Golden rice is genetically modified in order to produce beta carotene, which is not normally produced in rice. Beta carotene is convereted into Vitamin A when metabolized by the human body. We need Vitamin A for healthier skin, immune systems, and vision.

What happens at the Pacific Ring of Fire?
Answer:
THE PACIFIC RING OF FIRE Is an area around the pacific ocean with a lot of volcanic activity. magma is under the surface and lava is above the surface.
The Ring of Fire is home to 75% of the world's volcanoes and 90% of its earthquakes. This movement results in deep ocean trenches, volcanic eruptions, and earthquake epicenters along the boundaries where the plates meet, called fault lines.
so in conclusion in the pacific area there is basically a lot of volcanic activity

General intelligence, commonly referred to as the “g factor,” is a wide mental capacity that affects how well on cognitive ability tests a person does. Thus, option B is correct.
What is general intelligence?It is possible to describe general intelligence as a construct made up of various cognitive skills. These skills enable people to learn new things and resolve issues.
Underlying specialized mental talents in domains like verbal, spatial, numerical, mechanical, and mechanical abilities is this general mental capacity.
It is hypothesized that general intelligence influences how well people perform on all cognitive tasks.
You can relate general intellect to athletic ability. A person may be an exceptional runner, but this does not automatically make them a great figure skater.
Therefore, Dr. Ron supports the notion of general intelligence.

Answer:
D. Einstein's theory was difficult for many people to understand.
Explanation:
Einstein’s theory of general Relativity was largely Ignored for three decades because scientists at the time thought the theory was too complex compared to Newton's.
Therefore, it took long before the general science community accepted Einstein's theory of general relativity because Einstein's theory was difficult for many people to understand.

Answer:
The correct answer is they both have rings around them
Explanation:
Saturn and Uranus are both planets in our solar system; indeed Saturn is the sixth planet while Uranus is the seventh planet. Besides this, Saturn and Uranus are giant planets, this means they are composed of gas or similar materials and they are massive. Moreover, as giant planets these two planets have a ring system, which means around them, there are dust and other particles that orbit the planet and form rings; although, in the case of Saturn these are massive and more visible. According to this, Saturn and Uranus are alike because they both have rings around them.

There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.
